House of Antaak
From Star Trek: Theurgy Wiki
One of the most famous minor Houses, though not for any good reason. Antaak was rejected by his father, Gorlaq, for becoming a physician, though Antaak became House head after his father died in battle against the Tholians. Antaak himself was the doctor in charge of attempting to genetically engineer Klingons with Augment Earther DNA, which ended in disaster when a mutated flu caused thousands of Klingons to become QuchHa’. And Antaak’s son, Krit, murdered Chancellor M’Rek, for which he was discommended and executed. Antaak’s grandson Hurghom was instrumental in curing the Augment Virus – but he was the last of the line, and the House of Antaak died with him.
